Huey & gamma

I recently got a Pantone Huey to try to get some objectivity into my color management (a slow learning curve!). Two questions:
1. Can anybody tell me how to find out what gamma and white point are being used in the profile the Huey generates? The ColorSync Utility (which the Displays pane of Sys Prefs brings up when you select a profile and choose "Open") doesn't seem to tell me, or I don't know how to get this info out of the numbers it gives.
(Maybe a complication here: the Huey's own Sys Prefs pane offers nine different "color settings," with no indication of what you're choosing when you choose one -- do they all call on the same ColorSync Profile??)
2. Does everybody / anybody / most people, swear by the gospel of for example
http://docs.info.apple.com/article.html?artnum=302827
(linked from the Aperture Support page), that we should be using PCs' 2.2 gamma rather than Apple's unusual 1.8 native? Is this true if you're aiming to print as well as for web?
If I can find out what gamma and w.p. the Huey is choosing, I'd like to know whether they're what I want. Any help welcome. I should sign this

Charles -
I don't use the Huey but from what I know it's an exceedingly simple version of higher end calibrators. So, it may not give you the control over the settings that you'd get from other devices. I use an Eye-Photo with Eye-one Match software.
You should contact Pantone to cut to the chase and get the information you need.
About color management and that Apple document, yes, it is accurate. The idea of PC 2.2, Mac 1.8, should be thrown out as it's archaic. 1.8 is not native to Apple and has not been so for a long time.
Most folks calibrate to D65 and 2.2 gamma. There is one primary reason from straying from that: on lcd's (including laptops) sometimes native white point is the better setting (it'll give you more color gamut and many lcd's are close to D65 anyway).

Is Huey any good?

I'm using an Apple 20" LCD, and I've done the software calibration and created a custom monitor profile. However, the more i learn about colour management, the more i feel i should calibrate my monitor corectly, ie using hardware. Bearing in mind im just an amateur photographer, and the photos i take are primarily for personal use can anyone recomend the new Pantone Huey or similarly priced colour calibration tool?
Cheers,

I just finished a review for PPA mag. In a nutshell, it's a decent device and actually pretty fantastic at this price point. But it's designed for a color management phobic user who wouldn't know a profile from a pickle. It's very easy to use and pretty fast. I wouldn't trade one in for an Eye-One Display-2 or better. I have a bit of a beef with the ambient light tracking such that I think users should control their environment rather than adjust the calibration. But lets face it, the users it's designed for (hobbyist more or less) can't or will not control their ambient conditions. So it's kind of interesting "fix".
On an Intel 20" iMac, it did a nice job using the default target values (they correlate to TRC gamma 2.2, CCT 6500K). The control panel wouldn't load on the Intel (a common issue).
Bottom line, if you're too thrifty to get an Eye-One Display or OPTIX or the idea of color management freaks you out, this is a great product and way, way better than eye-ball calibration (Adobe Gamma which even Adobe no longer supports or recommends).

Make "Adobe Gamma" available to Lightroom users

]The topic pretty much speaks for itself.
]While I respect the superior nature of software/hardware based calibration
tools (Colorvision
b Spyder
, Pantone
b Huey
, GretagMacbeth
b Eye-One
), until I can afford a new monitor I will wait to purchase one of these solutions. In the mean time
b Adobe Gamma
would be a very useful tool to me and surely others. I'm honestly surprised that this piece of software was not included with
b Lightroom 1.0.

Uhhhh, please no Adobe Gamma in lightroom, CS3 or any product.
It was nearly impossible to get Adobe Gamma to work correctly for colors. Maybe a lucky few made it work.
With CS & CS 2 you were better off deleting Adobe Gamma from the startup group. Then using the color matching profile for your monitor.

Can't find Adobe Gamma to use to calibrate monitor

I have Photoshop Elements 6.0 and wanted to calibrate my monitor using Adobe Gamma which I understand comes with Photoshop. When I search for Adobe Gamma, I can't find the application. Any suggestions on how to find this, does the program have to be re-installed?

Despite what you may hear or read it is impossible to calibrate and profile a screen by software means only. All these programs rely on you 'eye-balling' the screen to assess when its set correctly - which can be hit or miss. None of them produce a profile which is also needed.
If you are serious enough to want to ensure that your screen is accurately rendering images then you need to purchase a hardware colourimeter like a Huey, Eye-one or Spyder - there are others as well.
Please note though that these will only ensure that your screen is showing your images correctly. It will not guarantee that prints will match the screen because a whole new set of rules apply to printing. It's not too difficult once you understand the basics and find a formula that works for you.

Momentary gamma shifts in PS-CS6 composed image h.264 video

Before I finalize a bug report, wonder what others are seeing?
Having discovered the problem in a more complex scenario, I've narrowed down to a simple set of jpg images placed sequentially in a video group, and exported as an h.264 video from Photoshop PS6. All is on Windows 7 Professional SP1, all software involved completely up-to-date.
I first noticed the gamma shift using the 'High Quality' preset. It occurs with variations on Vimeo 29.97 and Youtube 29.97 presets. The gamma problem does not occur on HD 720p or 1080p 29.97 presets.
When I view the resulting video through Quicktime, I see a gamma shift for a moment on the first image, making it look washed out. After another moment, the gamma goes back to normal. On other players such as Windows Media or VLC, no such shift is visible.
Interestingly, the shift comes at 1 second when exporting to the Vimeo 29.97 preset, or 'High Quality', while at 3 seconds on Youtube 29.97. Similarly, the shift back occurs at 2 seconds, or 6 seconds for Youtube.
What the gamma shift looks like sounds like the now age-old Apple Quicktime fault on h.264. -- except it occurs only for one or a few seconds, then reverts to proper gamma, instead of continuing..
With the simple setup of single image (jpg) sequence, it occurs only on the first image. With a more complex scenario, some actual videos included, I've seen it occur on every jpg -- or on some -- in a sequence.
This is very repeatable here - 100%. Anyone else who's noticed it? I'm on the CS6 trial, and still thinking whether to purchase, or go on the Creative Cloud.
Regards,
Clive

We're seeing a worse issue when exporting in H.264 and playing in QuickTime 10.0 (Mac OS 10.6). We are using a custom size video to fit a spot on our website (398x498). When exported and played in QuickTime 10.0 the white inverts throughout the video (back and forth). The same issue is not seen when viewed in VLC or QuickTime 10.1.
This is how the video should look:
And this is how they are appearing:
But like I said, the issue is very specific to QuickTime 10.0 on Mac 10.6. VLC, Flash, Chrome, FireFox all play it correctly.

How to change document gamma (or create a "false profile")

Although there has been much recent criticism of the notion of "false profiles," generally associated with the person who espouses it, I would like to be able to convert a document which is in, e.g., Adobe RGB with a gamma of 2.2 to one of the same colorspace but a gamma of, say, 1.5. Although I can do this via the color settings dialogue, creating a new setting with the name, e.g., "gamma 1.5," and although at the time of creation of the new setting the document does indeed become lighter, nonetheless the setting does not "stick." That is, if I leave that document and later try to apply that same setting via edit>convert to profile, nothing happens. I'd greatly appreciate someone giving me some pointers on how to establish a setting such that it appears and is functional in the edit>convert to profile list. I'm working in CS2 in OS10.5.6. Many thanks

The Red, Green and Blue tone response curves are kept separately in the .icm file. You can see that if you open an .icm file in Apple's ColorSync Utility.app. In the case of AdobeRGB1998.icm you'll find that each of those curves has an identical Gamma of 2.199, but they're stored and display separately.
You would need access to a profile generating application to change that, and you'd need to know what you're doing.

FCP "Export - QuickTime Movie" gamma shift

Above is an example of what happens when I do a direct export in Final Cut Pro, using the Export -> QuickTime Movie function. As you can see, the image is significantly brighter and the colors are a little more washed out (this image isn't particularly colorful, but trust me, it washes them out). I always thought the Export -> QuickTime Movie meant the image would not be compressed--that it was a straight export using the sequence settings.
The image you see above was shot natively in ProRes 422 (HQ) using an Arriflex Alexa. It has never been transcoded. The bottom image is what it looks like using Export -> QuickTime Movie. Totally unacceptable for a piece of professional software, if you ask me.
I can't express how infuriating this is, to have everything looking perfect in FCP and then exporting only to have it look like garbage. I've been able to play with gamma correction a bit and have gotten it PRETTY close to the original look, but this seems like a horrible workaround.
Anyone else know why this is happening? Is there a fix for this?
I'm working with FCP 6.0.6 and QuickTime 10.1.

Sure thing, Meg.
Here's a source clip with "approximate" gamma correction:
"Approximate" gamma correction makes the image look flatter within Final Cut Pro than it actually is.
Now, the very same clip and frame, but with gamma set to "Accurate" :
Now, things are switched. The exported image looks flatter than the source clip within FCP.
Here's another tidbit of info--the frame from my first post was professionally color graded and exported as a self-contained movie--so there were no filters, FCP or otherwise, being applied there. But the difference is just night-and-day to me.

How does one get huey pro to start up when computer starts in morning

Huey Pro is a sensor that measures and monitors the light in the room so that colors are rendered as acccurately as possible. Once I calibrated the screen and device, it should fire up when I restart the computer but it dos not. the icon in the system folder when clicked, says that the system preference folder needs to restart, the it will fire up.
So How does one get this to start early.
Robert

Hi Robert
I am not sure that you can make the Huey Pro work correctly.Worked fine on windows but it was the one programme for me that I have never had success with on the Mac.
I have checked the Huey web site for info but the support seems to have stopped.
So the only way I can do it is to wait until the Icon is in the top right section of the screen,note that a white cross is in it and then click on the Icon in the dock open up the programme until the Start bit occurs then just click the close button.That fixes it for me.

CS4 - Is there a way to adjust gamma for second monitor or send to overlay?

One thing that is evident when I edit in Premiere CS4 using the AVCHD 1080i 60 template is that the preview in the second monitor, which in my case is my TV set connected using a DVI to HDMI cable, is that the output is too dark compared to what it should be. Darker areas of the frame sometimes even get crushed into black when the same footage, when played directly from the camcorder, or even burned to blu-ray and played, is noticeably brighter and at the right black levels.
This doesn't happen when editing in Vegas Pro 8, or when the untouched footage is played through other video player, including Windows 7 Media Center.
A workaround for this problem can be to go to the graphics card control panel, in my case ATI Catalyst, and adjust the gamma for the second monitor, with the problem being that when you're done editing in Premiere you have to go back to the normal gamma. At one point I had setup two profiles in Catalyst with shortcuts and it worked well, but one day Catalyst simply lost the profiles and noticing how buggy it was I wasn't going to keep creating profiles so that Catalyst would delete them.
So my question is, since it's not in the preferences, is there some settings file or registry address that I can tweak to make Premiere display a brighter gamma of my choice?
And this may be a dead end, but is there a way to send the output of the second monitor to the overlay so that it can take advantage of the graphic's card video capabilities and display video smoothly? It's nice to have a preview of the timeline, but it's rather annoying if I have to go to the Catalyst control panel and adjust gamma before editing and after editing and that motion is jerky and not interlaced when I'm editing interlaced content.

You need the VESA mount option. That way your minimum angle would be completely vertical and you could open it to a negative 10 degrees.
Hope this helps.

AE CC and the Rest of Adobe Apps - ProRes Quicktime Render Gamma Problem Back AGAIN

Hi ---
With this version I am back to square one with AE NOT being able to render out correct gamma exporting to PR4444 -
Scenario (And this matter NOT whether I use Color Management or Not)
1) I open a Clip in AE or PPRO (In this case a TIFF Sequence RAW'ed from Lightroom)
2) I switch back and forth between Lightroom and AE and the images are identical in color and gamma
3) I export to PR4444 and open in Quicktime Player or FCPx and the Gamma is off.
4) If I re-import the exported file into AE - AE reads the file with a diff. gamma and the result appears to be identical with source
But it is no good that the result only looks the way it was intended in AE ! --- The poeople on the web are not viewing the movie in AE but with other players.
If i open that same tiff sequence in the quicktime player pro and export to PR4444 the results are 100% identical.
I find it highly frustrating that a company so higly regarded with so amazing software is NOT able to render out an image correctly...
This problem has been around since forever and I find it higly disturbing that this issue has not yet been addressed.
As of now I have no choice that to ditch AE and PPRO.... I WANT the images I work with to look the way they do in the app while color grading... What point is there in CG'ing images to perfection
if adobe cant even render out the results....
As I stated it does NOT matter whether I am color managing or not... Results are lighter in gamma when viewed in anything else than AE or PPRO !!!!!!
The amount to correct back is approx. a gamma of 0.9
BTW --- When in 32 bit how come I cannot set a gamma of 0.905 why is the gamma limited to two digits after the comma... 32 bit has MUCH more to offer !!!!

Thanks Todd,
I have tried those tips before. Unfortunately, I haven't had great success with them in this case.
When I reserve the 16GB of RAM for other apps and RAM preview a comp containing multiple Prores 4444 footage layers, it plays back and retains the cache as expected. However, the 2nd RAM preview of another comp in the same project containing multiple Prores 4444 footage layers stays stuck in "Initializing Background Processes." A check with Activity Monitor usually shows aeselflink processes that are hung up.
This has been my experience until I came upon the work-around of precomping Prores files.
To demonstrate, here's a screen shot of the stuck process with the memory settings I used -
I rebooted the system and tried 2 more times with the same result.
If I simply precomp the Prores 4444 footage layers as demonstrated in the video, I get smooth RAM preview caching and performance. This works even if I allocated less RAM to other applications in the Memory and Multiprocessing preferences (hence the 6GB setting from earlier). With the work-around, AE runs smooth with no hiccups and RAM previews behave as expected.

How to disable Adobe Gamma in Windows 7?

I have a new PC running Windows 7 and a new monitor. I want to color-calibrate the monitor using Spyder3, as I've done in the past with Windows XP. I cannot, however, locate Adobe Gamma in the msconfig "Startup" folder on Windows 7 to de-activate it. Has it been eliminated? Can I run the calibration program without taking this step? Many thanks in advance.

I'm loading CS5 (upgraded from CS3). It's the computer OS that I've had to remove it from before - and it doesn't appear in the Startup folder, unlike in Windows XP's system. (Or in the Control Panel, although there is a "Color Management" folder that lists color profiles I've downloaded from Epson when I downloaded my printer drivers for Windows 7).
So I guess Windows 7 doesn't include it, and I am free to do my calibration. Adobe's tech support phone line is closed for the weekend so I am turning to you forum experts. There must be someone out there who has encountered this in setting up a new computer system and loading PS onto it. Thanks for the input from both you and John.

QuickTime 7.1.6 Gamma/Color Shift Is Demonstrable

You can easily see the undesirable behavior of gamma/color shifting when playing H.264 codec movies in Apple's QuickTime Player.
Download any Apple HD (1920x?) QuickTime Trailer. Open and switch view to Double Size. The movie will immediately become darker with a pronounced gamma and color shift.
Reopening the movie switches back to the correct gamma and color.
I reported this bug, and since it's so easy to demonstrate, Apple should be able to fix it once and for all.
PowerBook G4 17 Mac OS X (10.4.9) QuickTime 7.1.6
PowerBook G4 17

I think you may find some will argue with you. DV and H264 at normal size look too bright and washed out for a lot of people, and are not the correct amount of darkness they should be. Fortuately when they're compressed to MPEG-2, if that's where you headed, they get the contrast back again.
Playing the move doubled up is one of many work arounds to the problem. But the problem isn't the one you think it is. You're right about the fact that it should be fixed once and for all.

Safari 4 Color and Gamma STILL Washes Out -- NOT Solved 7/4/2009

OK, just bringing this back to the top:
http://discussions.apple.com/thread.jspa?threadID=2032159&start=0&tstart=0 is listed as 'Solved', but that was totally premature. The alleged fixes range from the usual repair permissions, trash Safari prefs, reboot, etc., but it's all temporary, at best.
A CLEAN install of the OS to a virgin partition, followed by permissions, repair, combo updater, apply all related Safari, repair permissions, delete, shutdown and reboot leaves you with the same issue as soon as you sleep displays, go to screen saver, use FUS, and come back in with Safari 4 already running, you will get the screen wash as further described here:
http://gallery.me.com/frederico/100070
Posted Elsewhere:
Gamma settings within Safari 4 windows since upgrade will "degrade" (read: darken and stratify) when scrolling the window contents, using either scroll wheel, arrow keys, or mouse on scroll bar. Text also becomes progressively fuzzy and its opacity decreases until the entire window is black.
Moving another application window in front, or minimizing and maximizing the errant window, moving or resizing it in any manner, or using the 'Force Repaint' command will restore the appearance immediately. I can capture screenshots of it, but cannot use your included screenshot command, as the mere act of dropping down the report slider forces repaint.
Quitting Safari, rebooting machine, or just logging out will "cure" the problem for a short time, but it returns fairly quickly. I do not believe I have any third party plugins causing the issue; I removed several and the problem still crept back; each user account, including a freshly created test account sees this error.
This can fairly regularly be triggered by sleeping the displays or entering locked screensaver, logging in, and going to several sites such as Daring Fireball, Mac OS X Hints, and anything displaying PNG and Flash combos.
Perhaps related: I updated to 10.5.7 at the same time, and when I restarted, noticed that the gamma profile on my center screen (of five LCDs) was severely washed out. Switching back and forth between any other color profile in Displays and back to my calibrated profile will cure the wash -- until I log out and back in. Each user account, including a freshly created test account sees this error.
Have also clean installed OS X 10.5.4 and updated to a10.5.7 using combo updater; then installed and updated Safari 4. Problem follows Main screen (menubar host) on each of five LCD displays on three ATi video cards on Mac Pro Quad 2008.
Getting ready to restore back to Safari 3 and 10.5.6 from clone; this behavior is becoming tedious.

Now THAT is interesting. I typically do not have two Safari windows open and active on the same screen; I usually have three or more Safari windows open, but each is on its own screen, using tabs within each.
I think it's fascinating to see that the content is only affected in one window on the same page.
Can you elaborate as to your trigger? Is it FUS? Screensaver? Other?
The suggestion in either this thread or the other to switch the window momentarily to another screen to clear the problem until the next FUS or screensaver event is my current favorite fix. I have hotkeys assigned to move a window from one screen to another, anyway, so when I return to a user session from login to see Safari schizing out, a quick screen-swap toggle clears the issues until I allow a screensaver (but not always) or engage FUS (always) and see the issue return.
Do you have multiple screens? Can you reliably resolve the issue by swapping and returning, rather than being forced to quit Safari?
One thing to note about the screen swap, is that when this issue is occurring, there is a tremendous lag (a solid second or so) before the window is actually moved to the other screen, and a comparable lag when returning. IOW, there is an observable and HUGE processor spike as well as a memory-use spike (seen in Activity Monitor, top, and iStat Menus) as it deals with moving the visual display (be it plain text or graphic or video content) when this bug is active, but the same action two seconds later, or the same action in any other program, nets near-instant screen movement in response to the global hotkey action.
So, whatever it is that is borked between Safari and Core Video is not just an interpretation/ColorSync/disply error; it seems also to be leaking memory and having runaway processor cycles, as well.
There are times when Safari, with less than ten or twenty tabs open starts eating pretty close to 2GB of RAM, and will dominate a single processor to near 100%, *without* any windows actually containing very much in the way of images, and certainly no Flash or even QT.
I know this sounds a bit arrogant and spoiled, but thank God I have 8 cores and 8GB of RAM; I cannot imagine how this bug might feel on a single core machine with less than 2GB of RAM.
